Bar owner Salvatore Calabrese pours out the mixed ingredients into a glass as he attempts to create the world's most expensive cocktail at his bar in London on Oct. 11. Calabrese blended 1770 Kummel Liqueur, circa 1860 Dubb Orange Curacao, 1778 Clos de Griffier Vieux Cognac and circa 1900 Angostura Bitters to create "Salvatore's Legacy," at a cost of $8,800 a glass. The event was attended by officials from the Guiness Book of World Records and was an attempt to break the previous record set by "The Skyview Bar" in Dubai whose cocktail cost around $6,000 a glass.
